I can't see why the Maquis are considered such a threat. We learn that Starfleet intelligence has a spy within the terrorists in this episode. Ensign Ro also managed to penetrate their network, as did Tuvok, as did Seska, as did Boone. You begin to wonder if there are any actual Maquis in the Maquis, or is the whole thing just a massive group of intelligence operatives spying on one another?

Plotline

When Maquis leader Eddington resurfaces, Sisko is determined to capture him. But as Eddington consistently outwits the Captain, Sisko becomes more and more obsessed - to the point where he is willing to threaten entire planetary populations to get what he wants.
